+# Fase 1: EasyPanel Migration (Week 1-2)
+
+Target: Migrar 108 containers Docker para VM Proxmox
+
+## 1.1 Criar VM Docker Host
+
+```bash
+qm create 200 \
+  --name easypanel-docker \
+  --memory 32768 \
+  --cores 8 \
+  --net0 virtio,bridge=vmbr0 \
+  --scsi0 rpool/vm-disks:200 \
+  --ostype l26 \
+  --boot order=scsi0
+
+# Install Ubuntu 24.04 LTS
+# Via Cloud-Init ou ISO manual
+```
+
+## 1.2 Instalar Docker + EasyPanel
+
+```bash
+ssh root@10.10.10.200
+
+# Docker
+curl -fsSL https://get.docker.com | sh
+
+# EasyPanel
+curl -sSL https://get.easypanel.io | sh
+```
+
+## 1.3 Backup Containers Actuais
+
+```bash
+# Em easy.descomplicar.pt
+tar -czf /tmp/easypanel-volumes.tar.gz /var/lib/easypanel/projects
+
+# Transfer para PBS ou storage temporario
+scp /tmp/easypanel-volumes.tar.gz root@cluster.descomplicar.pt:/mnt/migration/
+```
+
+## 1.4 Migrar Containers (Batch 5-10)
+
+Batch 1 (nao-criticos para teste):
+
+```bash
+# Containers teste: dev environments, staging
+# IDs: 1-5
+
+# Por cada container:
+1. Exportar env vars do EasyPanel
+2. Exportar docker-compose.yml
+3. Copiar volumes
+4. Recriar em novo EasyPanel
+5. Testar health endpoint
+6. DNS cutover se OK
+```
+
+Workflow Batch:
+
+```bash
+for container_id in 1 2 3 4 5; do
+  # Export config
+  curl -s http://easy.descomplicar.pt:3000/api/trpc/services.get \
+    -d "serviceId=$container_id" > config_$container_id.json
+
+  # Copiar volumes
+  rsync -avz /var/lib/easypanel/projects/$container_id/ \
+    root@10.10.10.200:/var/lib/easypanel/projects/$container_id/
+
+  # Recriar service (via EasyPanel API ou UI)
+
+  # Test
+  curl -I http://10.10.10.200:PORT/health
+
+  # DNS cutover (se health OK)
+done
+```
+
+## 1.5 Validation (24-48h por batch)
+
+```
+Monitoring:
+- Uptime checks (UptimeRobot ou similar)
+- Error rates (logs)
+- Performance (response time <500ms)
+- Cliente feedback
+
+Rollback triggers:
+- >2 containers falham consecutivamente
+- Cliente reporta down
+- Health checks fail >10min
+```
+
+## 1.6 DNS Cutover
+
+```bash
+# Baixar TTL para 300s (5min) 24h ANTES
+# Ex: Cloudflare ou dns.descomplicar.pt
+
+# Cutover:
+A record: old-ip -> NAT port forward para 10.10.10.200:PORT
+
+# Monitorizar por 1h
+# Reverter se problemas
+```
+
+## 1.7 Rollback Procedure
+
+```bash
+# Reverter DNS (TTL 300s = 5min propagacao)
+# Reactivar container antigo
+# Investigar causa falha
+# Re-tentar apos fix
+```
+
+Batch 2-N: Repetir ate 108 containers migrados.
